Using 'were' when the subject is 'I' is called the Subjunctive Mood. There is a grammatical difference between using was or were in some structures with "were" signifying something that is an impossibility where as 'was' is something that is possible With "Wish" - in a wish structure you should only use 'were'; using 'was' is incorrect as you are wishing for something that you don't have. I wish I were smarter. (not) I wish I was smarter. With Conditionals - It is possible to use either "were" or "was" depending on how possible the condition is. If I were the president, I would... (this is extremely unlikely as I'm too lazy:) ) If I was wrong, I'm sorry (definitely possible as i make mistakes a lot) While this grammatical difference is well defined, fact is most native speakers (and indeed some teachers) don't know or care about the difference.

Hi Sara! We use I was. But in conditional sentences we use I were For example : If I were you, I would do it. Remember that we just use I were in these sentences! However sometimes native speakers say I was in conditional sentences but this is usually wrong. Hope this helps!😁

Salaam Sara, In English the custom is to use I was in all simple past situations. However, I were is the better option if we are using conditionals in the idea of giving advice to others. This is best illustrated in this phrase: If I were you, I would learn Spanish after finishing English. This is advice that is given to another person as a conditional; he advises the person to learn Spanish when he completes his English courses. In ALL other cases, use "I was."

While it's considered "wrong" to say "I was" in sentences like "I wish I were rich," the fact is that "was" is widely used and accepted even among educated people in sentence like that. So I wouldn't worry about it too much if I *were* you. (I try to use "were" appropriately in these cases, but I do forget sometimes.) People will understand you either way. But if you use "I were" in a non-conditional sentence, ("I were happy to meet you,") it will sound very strange and people will be confused.

hello I were is wrong
